But if you were nice you could of just said "hey you mean white is ground dont you?"
White is not ground.
It is in his case of only having the two wires. If he had the three wires then YES green would of been the ground. The white is the common ground in home wiring where the green is one that would go to a ground source following a ground for the entire home to a ground point somewhere going into the ground. He has white and black. Black is your power source and the white is the common netural ground to complete the circut.
In all cases the neutral (white) wire from the fan assembly should be attached to the neutral (usually white) lead from the house wiring. Note that if you encounter a white wire with a marking piece of colored tape attached, this could be used to signifiy it is being used as something other than a neutral.
The ground (green) wire or wires from the fan assembly should be attached to the ground (usually bare, sometimes green) lead from the house wiring. Some older houses may not have a separate ground lead and use the metal conduit and electrical boxes as ground. In this case you would attach the ground wire from the fan to the electrical box (and/or mounting plate) with the appropriate screw or clip.
